A Small Story

Once upon a time, in a small village, there lived a curious boy named Aarav. He loved asking questions like “Why does iron rust?” and “How does soap clean dirt?”
One day, Aarav’s teacher gave him a small chemistry kit. Excited, he mixed vinegar and baking soda. Suddenly—fizz! Bubbles came out. Aarav learned that this was a chemical reaction producing carbon dioxide gas.
The next day, he observed that a cut apple turned brown. His teacher explained oxidation. Aarav realized that chemistry was not only in books, but everywhere around him—in food, air, water, and even his own body.
Years later, Aarav became a chemist. He created medicines that saved lives and eco-friendly products that protected nature. He always said,

“Chemistry is not just a subject; it is the science of life.”

And that curiosity changed the world 🌍🔬
